Milpa Gardens

Milpa Gardens is notable for showing the reasoning behind its advice. Planting dates are tied to local frost probabilities, while companion-planting suggestions are labelled by confidence and linked back to their evidence. That means familiar claims such as the Three Sisters can sit alongside less certain pairings without pretending that every gardening tradition has the same scientific support.

The planner connects those explanations to day-to-day work: users can arrange beds, see what can still mature before frost, diagnose visible problems and keep a diary of plantings and freezes. A garden remains on the current device without an account, and optional sign-in adds cross-device backup and shared garden circles. English and Spanish are presented together throughout much of the site. Milpa suits gardeners who enjoy experimenting but want a visible line between established findings, promising trials and well-labelled hunches.
